Hey I need some input on vgx pads, I just order a set from summit racing for my 93 rx7 with slot rotor for the rear and the rep told me that vgx is a good brand? I am not too familair with that brand so I need to know how good r there. also I pay only $16.00 for pair plus shipping very cheap compare to ebc red stuff. please reply because i don't want o mess up my rotors. khris
